Abstract: A power supply for supplying power to a chipset includes a first voltage regulating circuit, which is configured to convert an applied power supply signal into a group of first supply voltages, and a second voltage regulating circuit, which is configured to convert the applied power supply signal into a group of second supply voltages. A control circuit is provided, which is configured to selectively enable the second voltage regulating circuit to generate the group of second supply voltages. An output discharge circuit is provided, which is configured to discharge an output stage of the first voltage regulating circuit in response to a transition of the first voltage regulating circuit from an active state to an inactive state. This transition of the first voltage regulating circuit from an active state to an inactive state can occur in response to a change in magnitude of the power supply signal.

Abstract: A solid state drive (SSD) device includes nonvolatile memory devices, a controller, a main power supply circuit and an auxiliary reprogram device. The controller controls the nonvolatile memory devices. The main power supply circuit provides an operation voltage to the nonvolatile memory devices and the controller using a supply voltage provided through a power line. The auxiliary reprogram device provides an auxiliary supply voltage to the nonvolatile memory devices and the controller and generates a reprogram command. The controller is configured to, if the SSD is not powered, perform periodically at a first period a reprogram operation on the nonvolatile memory devices.
